A short and diastereoselective synthesis of newly reported aza-diketopiperazine (aza-DKP) scaffolds starting from amino-acids was achieved using domino Rh(i)-catalyzed cyclohydrocarbonylation/addition.
A rapid and atom economical multicomponent synthesis of complex aza-diketopiperazines (aza-DKPs) driven by Rh(I)-catalyzed hydroformylation of alkenylsemicarbazides is described. Combined with catalytic amounts of acid and the presence of nucleophilic species, this unprecedented multicomponent reaction (MCR) enabled the formation of six bonds and a controlled stereocenter from simple substrates.
